Packaging film comprising a sealing layer and a substrate layer

摘要

A packaging film contains a) a sealing layer of a mixture of from 50 to 80% by weight of a random terpolymer (I) of from 90 to 97% by weight of propylene, from 2 to 6% by weight of ethylene and from 1 to 6% by weight of a C4-C10-alk-1-ene and from 20 to 50% by weight of at least one ethylene polymer (II) b) and a substrate layer of a thermoplastic polymer. The novel packaging film possesses in particular good sealability over a wide temperature range.
